Yes, the mortgage insurance premium is now deductible on your federal return. The IRS recently began accepting taxpayer returns deduction for mortgage insurance premiums on a primary residence. 

Navigate to the Your Home section to include your mortgage insurance premiums reported in Box 5 of your 1098 form.

Note: Not all of the state products have been updated at this time; many of the changes require guidance from the states and those updates will be made once guidance is received from the affected states.

If you have already filed your 2017 return and receive a corrected 1098 form for the private mortgage insurance, you can amend your return to add the deduction if you itemized.

Note: Wait until your originally filed return is fully processed before amending. This will avoid errors with the IRS processing. Once the original return is fully processed, use the link below for amending instructions.
